[srslte-users] Internet Connectivity Extremely Slow

Hey Bennett,

It was just letting the ping on in what's about to become the UE IP
(default: 192.168.10.2), so that the eNB doesn't release the UE due to
inactivity, after the UE establishes the connection. But looking at the
latest logs, I don't think this will solve anything. I will try to come
back to you, once I find a fix.

Btw, I would suggest keeping the mailing list in Cc, as other people may
know how to fix this issue.

Kind Regards,
Francisco
